VALVE DEVICE.

Application filed July 20, 1908.

T 0 all whom it may concern:

Be it known that I, JOHN MILLER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Valve Devices, of whichthe following is a specification.

The present invention relates to valve devices which may be used for anypurpose for which they may be found to be adapted, but which areparticularly adapted for use in connection with what are known ascontinuous flow bath tubs. These bath tubs, which are used in thetreatment of diseases, although of comparative recent origin, are wellknown to those skilled in the art and need no minute description here.

One object of the invention is to provide an improved means whereby theflow of water is continuously maintained.

Another object of the invention is to provide means whereby the valve issecurely held in any position in which it may be set to provide a flowin excess of the minimum flow, and to make this means such that itcannot cut or injure the operator in manipulating the valve.

To these ends the invention consists in the features of novelty thatare, hereinafter described with reference to the accompanying drawing,which is made a part of this specification and in which:

Figure 1 is a view partly in section and partly in elevation, of a valvedevice embodying the invention. Fig. 2 is an elevation thereof.

The valve device has a casing, 1, having an inlet port, 2, and anoutletport, 3. \Vith the inlet port 2 communicates a pipe-section, 4,having an external shoulder with which engages a cap, 5, having threadedengagement with the casing. \Vith the outlet port 3 communicates apipe-section, 6, having an external shoulder with which engages a cap,7, having threaded engagement with the casing. The inlet port issurrounded by a valve seat, 8, to which is adapted a valve, 9, seatinginward or in the direction of the flow of water and guided by anysuitable means. Its movement away from its seat is limited by lugs, 10,formed on the interior of the pipe-section, 4.

The side of the casing is provided with an opening closed by a screwplug, 12, carrying Specification of Letters Patent.

Serial No. 444,430.

a stuffing box, 13, and through this stufling box passes an unthreadedvalve-rod, 14,10- eated at right angles to the stem, 15, of the valve,9, and carrying an eccentric, 16, which engages said stem. Thisconstruction and arrangement of valve-stem, valve-rod and eccentric isprecisely the same in all essential particulars as that shown in myapplication of even date herewith, Serial No. 444,429 and I do not claimit in this application.

Attached to the valve-rod is a hollow handle, 17, carrying a laterallyprojecting dog, 18, having a stem, 19, which passes through the bore ofthe handle. This bore is of three diameters. The portion of largestdiameter is occupied by an enlarged head or push button, 20, carried atthe upper end of the stem of the dog and the intermediate portion isoccupied by a coiled spring, 21, which exerts its pressure in onedirection upon the dog and in the opposite drection upon the handle. Thedog occupies a longitudinal slot, 22, in the handle to prevent it fromturning and its laterally projecting portion, which is cylindrical,engages a series of curved ratchet teeth on the inner surface of asector, 23, secured to the stuffing box or other suitable part of thecasing. To shift the position of the lever and there- ,by shift theposition of the valve, with ease,

the pressure is exerted on the push button and the dog thereby releasedfrom the ratchet, but the dog being cylindrical and the teeth curved thelever may be shifted without depressing the button. The sector ispreferably marked with graduations for approximately indicating to theoperator the volume of water flowing through the outlet port when thehandle is in any given position.

To provide for the continuous flow of water, the valve is provided witha perforation or passage, 24, which extends completely through it, fromface to face, and forms a by-pass through which a certain quantity ofwater may flow constantly whether the valve is seated or not.

\Vhat I claim as new is:

1. In a valve device, the combination of a casing having an inlet port,a valve seat surrounding said port, a valve adapted to said seat andseating inward, a valve rod, means for transmitting movement from thevalve rod to the valve for unseating the valve, a handle secured to thevalve rod, a dog carried by the handle and having a laterally projectingportion, a spring exerting its pressure in one direction upon the handleand in the other direction upon the dog, and a sector having a series ofratchet teeth, with which the dog engages, for holding the valve in anyposition in which it may be set for regulating the flow of water pastit.

2. In a valve device, the combination of a casing having an inlet port,a valve seat surrounding said port, a valve adapted to said seat andseating inward, a valve rod, means for transmitting movement from thevalve rod to the valve for unseating it, a handle secured to the valverod, a dog car ried by the handle and having a laterally projectingportion provided with a rounded working surface, a spring exerting itspressure in one direction upon the handle and in the other directionupon the dog, and a sector having ratchet teeth provided with roundedworking surfaces with which the rounded working surface of the dog isadapted to engage.

3. In a valve device, the combination of a casing having an inlet port,a valve seat surrounding said port, a valve adapted to said seat andseating inward, a valve rod, means for transmitting movement from thevalve rod to the valve for unseating it, a handle secured to the valverod, a dog having a laterally projecting portion, a spring exerting itspressure outwardly upon the dog and inwardly upon the handle and asector having ratchet teeth arranged on its internal surface with whichthe dog engages for holding the lever and consequently the valve in anyposition in which it may be set for regulating the flow of water pastthe valve.

4. In a valve device, the combination of a casing having an inlet port,a valve seat surrounding said port, a valve adapted to said seat andseating inward, a valve rod, an eccentric carried by the valve rod andengaging the valve for unseating it, a handle secured to the valve rod,a spring actuated dog carried by the handle, and a sector having ratchetteeth with which said dog is adapted to engage for holding the valve atany desired distance from its seat, for regulating the flow of Waterpast it.
